The fluid in the OPSs photo is external. All he know is it is losing oil and the engine shows external fluid marks. He assumes the fluid he sees is from the oil lost while he drives the car. He assumes the oil is leaking. He doesn't say if he's the original owner, how the car performs, whether it gets parked level on on steep hills, how he refills the oil, etc.If you clean it off, then drive it enough to lose a quart, do you wind up with oil all over the back of the engine, the firewall, and the underside? Or is it burning most of it? My 08 was going through almost a quart every tank of gas (while my daughter had it) until I installed new piston rings and valve seals.
